Abstract

This study investigated the prevalence, diversity, and intensity of ectoparasitic protozoa infecting Litopenaeus vannamei in traditional and intensive shrimp ponds. A total of 25 shrimp from each pond type were examined for the presence of ectoparasitic protozoa. Four parasite species were identified in traditional ponds: Zoothamnium sp., Epistylis sp., Vorticella sp., and Trichodina sp. In contrast, three species (Zoothamnium sp., Epistylis sp., and Vorticella sp.) were found in intensive ponds, with Trichodina sp. absent in the latter. The prevalence of ectoparasitic protozoa was higher in intensive ponds, with 44% of shrimp infected, compared to 8% in traditional ponds. The intensity of infection was also higher in intensive ponds, with an average intensity of 10.27, categorized as medium, compared to an intensity of 5.2 in traditional ponds, categorized as low. These findings suggest that intensive farming conditions may contribute to increased susceptibility to ectoparasitic infections in shrimp. The study emphasizes the importance of monitoring and managing parasite infestations to reduce health risks in shrimp aquaculture systems.

Abstract

Puntius denisonii is a highly valuable ornamental fish that is in great demand in the international trade market. However, overexploitation and habitat degradation have led to a decline. Cultivation efforts with an optimal feeding strategy are necessary to enhance the Survival and growth of this species in a controlled environment. This study aims to analyze the effect of different feeding frequencies of Tubifex sp. worms on the growth and survival rate of P. denisonii larvae and determine the optimal feeding frequency and timing. This research was conducted from January 20 to 29, 2025, at Bogorian Aquatics Farm, Bogor City, using a completely randomized design (CRD) with three feeding frequency treatments: three times per day (A), four times per day (B), and five times per day (C), with nine replications for each treatment. The observed parameters included survival rate and water quality. Data were analyzed using ANOVA at a 95% confidence level, followed by the Least Significant Difference test. The results showed that feeding frequency significantly affected the growth and survival rate of P. denisonii larvae but did not significantly affect water quality. Parameters of dissolved oxygen (5.35-5.37 mgL⁻¹), temperature (27.30-27.41°C), and pH (7.97-8.00) remained stable across all treatments. The treatment with a feeding frequency of five times per day yielded the best results in enhancing larval growth and Survival compared to other treatments. Increasing feeding frequency in P. denisonii aquaculture can improve survival rates without adversely affecting water quality if the aeration system is properly managed.

Abstract

Sea turtles are keystone species in coastal ecosystems, playing an essential role in maintaining ecological balance by regulating the population of certain marine organisms and sustaining the quality of critical habitats such as seagrass beds and coral reefs. Their presence not only reflects the health of marine ecosystems but also serves as a key indicator of the success of marine conservation initiatives. This study evaluates the effectiveness of conservation area management in three sites in West Sumatera Province using the Evaluation of Marine Protected Area Management Effectiveness (EVIKA) framework, namely the Pieh Marine Protected Area on Pandan Island, Karabak Ketek Island, and the Ampiang Parak Conservation Area. A descriptive analysis was applied to assess the performance of each EVIKA criterion and indicator. The results show that the Pieh Conservation Area achieved a sustainable management status with the highest score in the input component, while Karabak Ketek Island and Ampiang Parak were categorized as optimally managed. The effectiveness of management across these areas is influenced by several key factors, including the strength of legal frameworks, the availability and competence of human resources, institutional capacity, and the level of community participation. This study recommends enhancing multi-stakeholder collaboration, strengthening the role of community-based monitoring groups (pokmaswas), and implementing participatory monitoring systems that are community-driven and adaptive to the dynamic changes of coastal environments.

Abstract

Ectoparasite infections frequently affect gourami fish during the seed (juvenile) phase. Immersion in piper betle extract can be a natural alternative treatment to reduce ectoparasitc infections by utulizing its bioactive compounds. This study aims to identify and analyze the prevalence and intensity of ectoparasite infecting juvenile gourami. The experimental design consisted of four treatments with three replications each. Treatment P1 (control), treatment P2 (piper betle extract at 150 mg/L), treatment P3 (piper betel extract at 200 mg/L), and treatment P4 (piper betle at 250 mg/L). The findings indicated that treatment P3 was the most effective in reducing the prevalence of Trichodina sp. (40%) and Dactylogyrus sp. (53%), and also achieved a survival rate of 90%. Treatment P4 was able to reduce the prevalence of Gyrodactylus sp. by 20%, as well as the Trichodina sp. (%), Gyrodactylus sp. (%), and Dactylogyrus sp. (%). However, the growth in length, absolute weight gain, and feed conversion ratio (FCR) were not significantly affected. The types of ectoparasite were found to infect juvenile gourami: Trichodina sp. (prevalence 40% and intensity 5 ind./fish), Gyrodactylus sp. (prevalence 20% and intensity 1 ind./fish), and Dactylogyrus sp. (prevalence 53% and intensity 2 ind./fish).

Abstract

Indonesia has the largest mangrove forest in the world. Surabaya City, in addition to being a center of industry and trade, also has great potential for ecotourism development and is known to have educational coastal ecotourism areas. Gunung Anyar Mangrove Botanical Garden, Surabaya, is one of the significant mangrove areas in Indonesia. The increasing popularity at KRM Gunung Anyar, Surabaya results in an increase in the number of visitors and is a challenge in itself in improving the quality of services, tourist attractions, and infrastructure to visitor satisfaction by maintaining and stabilizing visitor ratings. This study aims to analyze the effect of service quality, tourist attractions, and infrastructure on visitor satisfaction through perceived value as mediation. This research uses a quantitative descriptive approach with a sample of 150 respondents with a research instrument in the form of a questionnaire. The data analysis used is SEM WarpPLS 8.0. The results showed that service quality, and tourist attractions have a direct influence on visitor satisfaction through perceived value as mediation, while infrastructure has no direct influence. The existence of this finding shows the importance of perceived value by visitors in fulfilling visitor satisfaction which also sustainably strengthens the competitiveness of KRM Gunung Anyar, Surabaya with other tourist destinations.

Abstract

Koto Panjang Reservoir is used as a fish farming site using the Floating Net Cage (KJA) system. The development of KJA in Koto Panjang Reservoir provides economic benefits for the community but also has the potential to cause a decline in water quality. This study aims to analyze the concentration of chlorophyll-a around the reservoir where KJA is located. The survey method was used for observations at 4 stations with 3 replications. The characteristics of the four stations were based on variations in the number of KJA plots: station 1 (60 plots), station 2 (no KJA), station 3 (350 plots), and station 4 (600 plots). Sampling was carried out in the morning from 08.00 to 12.00 WIB. Chlorophyll-a was analyzed using the spectrophotometric method. The concentration of chlorophyll-a in the waters of Koto Panjang Reservoir ranged from 7,693 to 12,927 µg/L, classified as mesotrophic. The highest value was detected at station 4 (12,927 μg/L) and the lowest at station 2 (7,693 μg/L). There was a tendency to increase chlorophyll-A concentrations in line with the increasing number of KJA plots. Water quality in the Koto Panjang Reservoir, based on pH, temperature, clarity, dissolved oxygen, free carbon dioxide, and chlorophyll-a, still supports the life of organisms.
